GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 325,138, dated August 25,1885.

Application filed December 3, 188-1.

1"0 (LZZ whom it may concern.-

Be it known that I, JOSEPH D. West, of East Orange, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Gas-ltegulators, of which the following is a full, clear, and exact description.

This invention relates to that class of devices which are used for regulating the force of flow of gas either from a main pipe or from a meter to the servicepipc; and its object is to equalize the pressure of gas at the point of consumption, whether the gas in the sup ply-pipe be under heavy or light pressure, and whether the gas is being consumed at one or more burners in the same service pipe.

To this end my invention consists in the construction and combination of parts forming a gasregulator, hereinafter described and claimed.

teference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical section of my gas-regulator. Figs. 2 and 3 are transverse vertical sections at .r and 2/, respectively, of Fig. 4. Fig. 4- is a horizontal section at 2, Fig. 1.

A represents a receptacle which serves as a tank for liquid, either glycerinc 01' water, the liquid, 0, to be held therein serving to pack the loose joints between moving and stationary parts.

I; is an inlet-pipe extending up into the interior of the tank above the liquid'level.

I) and E are inverted boxes which I call gasometers, the box E being of larger size than box D. They are connected together by a bar or web, F, that rests on a fulcrum, G, on which the gasomcters are balanced to tilt up and down. The lower edges of the gasonieters enter the liquid to prevent the escape of gas.

H is a pipe or passage, having one end, H, in the gasometcr D above water, and the other end, H, in the gasoineter E also above liquid, while its middle or connecting portion passes below the liquid in the tank.

(No model.)

I is the outer or service pipe.

The inner ends of the three passages B, H and I have all free openings into the gasoineters; but the passage 11 is provided with a scaling trap or valve, consisting of a short portion of pipe or a ring, J, projecting down from the inner top of the gasometerD around the mouth of the passage into an annular cup, K, containing mercury or other heavy fluid.

L and M represent weights placed on top of the gasometers, whereby they are adjusted to deliver the gas at any desired pressure.

The operation is as follows: The gas enters the gasometer D through the passage B and leaves it at H, thence passing through the passage H H into the gasoinctcr E, and thence out at the service-pipe I. The weights M having been set for a certain pressure, if the supply of gas exceeds the consumption enough to raise the pressure, the gasomcter E will be raised, causing the gasometer D to tilt down and close the trap or valve J, thereby checking the flow of gas. \Vhcn the gas is consumed from the service-pipe enough to reduce the pressure below the standard, the weight M will depress the gasoincter E, thereby opening the trap or valve J, permitting the gas to flow. The weights may be so adjusted that a very slight variation of pressure will operate the trap or valve, thereby regulating the flow proportionately to the consumption, however varied it may be.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with two inverted boxes or gasometcrs connected together and balanced totilt 011a fulcrum, of atank containingliquid, in which the lower edges of the said boxes are immersed, an inlet-pipe and an outlet-pipe communicating freely with one of the said boxes, a free inlet-pipe for the other or second box, and an outlet-pipe therefor, serving as the inlet-pipe to the first-named box, and a trap or valve for the outlet of the second box connected therewith to be opened and closed by the tilting of the boxes, substantially as shown and described.

2. The gas-regulator consisting of two connected and balanced boxes or gason'1eters,onc

Ail

of larger area than the other, and a sealing trap or valve fitted for being opened and closed by the tilting movement of the boxes, whereby gas admitted to the smaller box is allowed to flow to or is cutoff from the larger box, according to the pressure in the latter, substantially as described.

3. The combination, with the tank A and the passages B, H, H and I, projecting up into the tank, and the passage H, connecting the passages H and H of the inverted boxes or gasometers D and E, the web F, connecting them, and the fulcrum G, substantially as shown and'describcd.

4. The combination, with the tank A, the [5 passages B, H, H, H and I, and the gasometers D and E, balanced in the tank to tilt over the mouths of the said passages, of the ring J, projecting down within the gasometer D,

and the annular cupK around the passage H, 20
